I have been told if I want to improve I need to build a base that is to run easy (70% MHR) for all my runs for three months.
After that I can start to do some speed training etc. If you have done it can you let me know if it was worth the time put into it?
The other option is to run just my easy days slowly it appears most of us run them too quickly anyway!
Any thoughts and views would be appreciated?
